For centuries, traditional healers have turned to the natural world to find remedies for common ailments. One plant that has attracted attention across cultures is Physalis, also known as ground cherry, goldenberry, or cape gooseberry. These small, bright-orange fruits enclosed in papery husks aren’t just a sweet snack—they’ve been used in folk medicine from Asia to South America.

Among the many traditional uses, Physalis has been linked to eye health and relief from eye infections. While modern medicine offers antibiotics and eye drops for serious infections, Physalis continues to be part of cultural practices where people seek gentler, plant-based support. Recent research suggests its antioxidant, anti-inflammatory, and antimicrobial compounds may explain why it earned such a reputation.
This article explores Physalis’ traditional role in eye care, the science behind its properties, and safe ways to incorporate it into a modern wellness routine.
What Is Physalis?
Physalis belongs to the nightshade family (Solanaceae), which also includes tomatoes and eggplants. The fruit grows inside a thin husk that looks like a lantern, protecting it until ripe.
Common names:
- Ground cherry
- Goldenberry
- Cape gooseberry
- Inca berry
Traditionally, different parts of the plant—leaves, fruit, and husk—have been used in herbal medicine for:
- Supporting immune health
- Reducing inflammation
- Calming respiratory issues
- Promoting skin and eye wellness
Why Physalis Is Linked to Eye Infections

1. Antioxidant Protection
Physalis is rich in vitamin C, carotenoids, and polyphenols, which protect eye tissues from oxidative stress. Oxidative damage contributes to both infections and degenerative eye conditions.
2. Anti-Inflammatory Properties
The plant contains withanolides, compounds that calm inflammation. Since eye infections often involve swelling, redness, and discomfort, this may explain traditional use.
3. Antimicrobial Activity
Some studies suggest Physalis extracts show antibacterial and antifungal effects, which could help reduce microbial load in mild eye issues.
| Active Component | Potential Benefit for Eyes |
|---|---|
| Vitamin C & carotenoids | Boosts immunity, protects eye tissues |
| Withanolides | Calms swelling and inflammation |
| Polyphenols | Neutralizes free radicals, speeds healing |
| Antimicrobial agents | May inhibit bacteria and fungi |
Traditional Uses in Eye Health

In certain Asian and Latin American folk practices, crushed Physalis leaves or diluted juice were applied near (not directly in) the eye to ease swelling and irritation. Others used teas or decoctions internally to strengthen immunity and help the body fight infections from within.
Important: Direct application of raw plant juice into the eye is not recommended due to potential irritation or contamination. Modern safe practice focuses on consuming the fruit as part of a nutrient-rich diet.
